This file contains commentary from night shift workers on shift work, shift lag and informal testing of the remedy No-Shift-Lag. These tests were used to establish the protocol for a proper trial conducted at a later date. This test was not a scientific trial where the usual double blind, placebo controlled, cross over, methods are used. Such a trial is in the next file called "Scientific test of No-Shift-Lag" The information below comes from interviews with night shift workers and their supervisors and is their opinion on shift work, shift lag and No-Shift-Lag.

1. Test of No-Shift-Lag at Moulded Wood Plant

Three eight hour shifts starting at 2300 hours on Sunday night and finishing on 2300 hours on Friday night. Thirty staff work rotating shifts. Day shift starts at 0700 and runs to 1500 hours and then the afternoon shift starts at 1500 hours and runs to 2300 when the night shift starts and runs to 0700 the next morning.

The rotation pattern is days, nights and afternoons on a weekly turnaround. The nature of the work is 50% physically demanding and the other 50% has a more mental component. Both exude a high toll on our workers especially at 0300 hours on a hot summer's night, which is made worse with the ovens running at over 200 degrees centrigrade.

Problems with shift work

Any problem with any staff member does not stay isolated with that worker as the nature of night shifts and lack of diversions, problems flow through the work force easily and almost everyone gets affected.

Specific Problems

Some specific problems encountered with shifts are: tiredness, insomnia, bitchiness, irritability, forgetfulness right through to family break ups. Tiredness leads to small jobs being missed or ignored, such as basic housekeeping, basic quality checks, clocking in and out. These small things when all compounded together become large problems very quickly.

Sick Days

These were investigated and found to be true sick days with workers ill, and not workers taking days off for other reasons. The illness of a large proportion of those who were off sick could be attributed to doing shift work. The sickness problems were: large number of colds and flu's, which were brought on by staff being run down with low vitality and unable to fight off infections, stomach problems by workers not eating properly and accidents caused by inattention which in turn was caused by fatigue and lack of quality sleep.

The trial using No-Shift-Lag

The trial started with a small group comprising of the supervisor who was having problems sleeping. One of the stack crew who had become easily upset and prone to seeing problems that were not really there, which required lots of calming talk. And an operator whose work quality was slipping.

By the end of day two of the trial the three users of No-Shift-Lag saw positive results. By the end of the first week the results were so encouraging the dam broke the planned orderly trial, had gone by the board and all the shift workers had a packet of No-Shift-Lag in their pocket.

By the end of the second week the shift workers had discovered that by using No-Shift-Lag during the night shift they gained the most advantage from No-Shift-Lag.

The positive benefits soon flowed. The work quality from the operators improved, the stackers problems disappeared and the night shift supervisor finally started to form a sleep pattern of quality and refreshing sleep.

Other staff members were showing obvious signs of improvement. They were starting to wonder about the ingredients of the No-Shift-Lag. The staff were referring to them as "uppers." "I don't know how they arrived at that comparison, but there definitely was a change of atmosphere around the factory."

Another effect was a "speeding up" of the natural body functions. Reducing constipation that most felt was caused by shift work.

Although most got a positive result from using No-Shift-Lag some did not and others felt that over use diminished its effectiveness. When shift workers only used No-Shift-Lag on the night shifts the remedies effectiveness returned to normal.

As for the comment that No-Shift-Lag has a n effect on a person sex life, this was not a formal question asked but if the rumour machine at the plant is be believed there are a few happy people in the factory. The supervisor is in this happy group and can vouch for No-Shift-Lag helping his sex life.


Overall the No-Shift-Lag trial was a success, its use along with other techniques to ease the strain of shift work has led to a happier, safer work environment.
We are considering making No-Shift-Lag available to workers in the same way we issue general safety gear.

2. Two Night Shift Workers at Synthetic Fuels Plant.

Age = 33 and 40 years old.
One working shifts for six years and the other for fifteen years.
Shift Cycle. Two days 7:00am - 7:00pm, then two nights of 7:00pm - 7:00am,
then four days off.

Both find shift work is fatiguing, feels like being run over by a bus. To remain "normal" both need to exercise heavily when not working. These activities include cycling, running, aerobics, pushing weights and golf. Therefore very little time for most other activities, like family and other close relationships.

Used No-Shift-Lag in the following doses:

1st tablet at 2300
2nd tablet at 0200 hours - (usually feels lousy at this time)
3rd tablet at 0500 hours - (usually feels real lousy at this time)0730 - bedtime after night shift
4th tablet on awakening - usually between 1300-1400 hours
This 4th tablet prevented the usual horrible dry mouth after awakening from a night shift.

Comparison between using and not using No-Shift-Lag on night shifts.

Not using No-Shift-Lag
Have main meal before midnight and a small snack "smoko" after midnight with minimal fluid intake after midnight otherwise woken up while sleeping with an urge to urinate. Although during night shifts we do have a "milo" at 0300 and again 0530 but no other fluid intake until waking in the early afternoon. When we awake we always have a dry horrible mouth and have to consume copious amounts of fluid to rehydrate the body. Usually irritable and annoyed with life after awakening.

Using No-Shift-Lag

During the night between 0200-0500 and after awakening the mouth does not feel as dry and horrible. This is with no change to food or fluid intake. Used to fee very thirsty in the afternoon between night shifts and no longer do after using No-Shift-Lag. Feel more able to cope with night shifts.

Better temperament and mood both on the actual night shifts and afterwards. Helped our relationships. Wife of one partner was totally surprised by her partner's positive mood and extra energy.

Don't feel so wacked in the afternoon after the night shift and now able to get up before noon which suggests we are getting a better quality sleep.

Comments form the manufacturer of No-Shift-Lag:

Although there have been comments about "uppers," increased energy and improved sex life, No-Shift-Lag is not like a stimulant or a sex stimulant (aphrodisiac). While these are genuine comments from shift workers it does not mean that No-Shift-Lag will increase energy, lift mood or improve your sex life. What has occurred is that the shift workers were fatigued and after getting quality sleep and becoming less exhausted and fatigued, they of course felt better and had more energy for everything including sex.
